do you think you have a swarm of bees?

if you think you have a swarm of honey bees, the first thing you should do is
go to

http://www.bbka.org.uk/help/do_you_have_a_swarm.php

Then, after clicking onto this link, if you still think they have a swarm of honey bees

(and not wasps or bumble bees) 

type in your postcode and you will receive a list of near-by beekeepers who are registered with the British Bee Keeping Association

contact one of them 

an experienced beekeeper will come and take away the bees, find them a hive, and a new bee keeper 

(members of the Bee Friendly Collective are on this list, as are many other bee keepers from the Todmorden area)
